Maximum power point matching method

A method comprising:

• performing a maximum power point (MPP) matching process, wherein the MPP matching process comprises moving a working point along a first curve of a power generator, the first curve reflecting a first external condition;
• setting a reference point, wherein the reference point is a past working point;
• comparing the working point with the reference point in a control cycle or control step;
• continuing the MPP matching process if the working point is substantially similar to the reference point;
• and
• changing the MPP matching process from the first curve to a second curve if the working point is substantially different to the reference point, the second curve reflecting a second external condition.

A method of maximizing a power generated by a system, the method comprising:

• determining a first reference power generated at a reference point;
• performing a power matching process, wherein the power matching process comprises moving a working point of the system into a matching direction;
• subsequently determining a second reference power at the reference point and maintaining or changing the matching direction dependent on a comparison of the second reference power and the first reference power;
• and
• continuing the power matching process by moving the working point into the matching direction.

A method comprising:

• finding a maximum power point (MPP) of a power generator system by applying an algorithm, the algorithm comprises a characteristic curve method;
• evaluating an irradiation condition by comparing a reference point to a working point in a first control cycle or control step, wherein the reference point is set in the algorithm;
• and
• adjusting finding the MPP based on the evaluation of the irradiation condition.

A method of maximizing power generation by a system comprising:

• applying an algorithm comprising a characteristic curve method around a first maximum power point (MPP) of the system;
• comparing a first power generation value before applying the algorithm with a second power generation value after applying the algorithm;
• determining if there is a change in an irradiation condition based on the comparison of the first power generation value and the second power generation value;
• and
• applying the algorithm around the first MPP or applying the algorithm around a second MPP based on the determination of the irradiation condition.
